eBay, Wal-Mart Search for Revved-Up Search Engines

Reuters reporting about eBay and Wal-Mart’s work to improve their search engines:

The search engine project takes time because eBay’s online marketplace has so much variable information from millions of listings that are described differently by each seller - something known as unstructured data in the tech world.

This is not much of a NoSQL story, but there’s something I’m reading between the lines: when talking about creating better search solutions making search work at scale is not mentioned, implying this is a solved problem. The focus is on handling unstructured data and creating better relevancy algorithms.

I have no details about the architecture of the new version of eBay search, but I have found this diagram of eBay’s Voyager in a slidedeck by Dan Pritchett from around 2007:
